Just So Stories addendum: How the stickleback keeps getting its stickles

Model organisms have been essential tools for genetics research since the field was formed.  Kelle Freel discussed the characteristics that make for a good model organism in a previous TME post.  Briefly, traits like short generation time, lots of offspring, … Continue reading

La vie en rouge … l’algue rouge

Best laid plans of a #NewPI … what happens to them? Well, they often get triaged for more urgent things that were triaged earlier for more urgent things that were also triaged even earlier for more urgent things … and … Continue reading

Is the neutral theory dead?

You might have noticed how the world of genetics was shaking as the giants of theoretical population genetics started discussing some of the most fundamental questions in the arena of Twittersphere. This happened after the publication of Andrew Kern and Matthew … Continue reading

Oh my ploidy … diploids evolve more slowly than haploids?

It’s been an embarrassingly long time since I last sat at my keyboard in a TME capacity (#NewPI chat doesn’t really count)! One year ago today, to be exact (writing this on 28 March, for publication on 29 March). Thus, … Continue reading

Are population genomic scans for locally adapted loci too successful?

Last Friday, Molecular Ecology released an interesting new systematic review online ahead of print. Colin Ahrens and coauthors at a number of Australian research institutions compiled results from 66 papers reporting tests for locally adapted loci based on either FST … Continue reading

The genomic architecture of ecological speciation

Speciation reshapes the ways genetic diversity is distributed in the genome — it’s been said that the establishment of reproductive isolation is essentially the evolution of genome-wide linkage disequilibrium. The “genomic islands of speciation” model of ecological isolation imagines genome-wide … Continue reading
